lt. Vanmeter of Colorado describes a boy of fourteen with
a severe extensive burn; a portion beneath the chin and lower jaw, and
the right arm from the elbow to the fingers, formed a granulating
surface which would not heal, and grafting was resorted to. The
neck-grafts were supplied by the skin of the father and brother, but
the arm-grafts were taken from two young puppies of the Mexican
hairless breed, whose soft, white, hairless skin seemed to offer itself
for the purpose with good prospect of a successful result. The outcome
was all that could be desired. The puppy-grafts took faster and proved
themselves to be superior to the skin-grafts. There is a case reported
in which the skin of a greyhound seven days old, taken from the
abdominal wall and even from the tail, was used with most satisfactory
results in grafting an extensive ulcer following a burn on the left leg
of a boy of ten. Masterman has grafted with the inner membrane of a
hen's egg, and a Mexican surgeon, Altramirano, used the gills of a cock.

Fowler of Brooklyn has grafted with the skin from the back and abdomen
of a large frog. The patient was a colored boy of sixteen, who was
extensively burned by a kerosene lamp. The burns were on the legs,
thighs, buttocks, and right ankle, and the estimated area of burnt
surface was 247.95 square inches. The frog skin was transferred to the
left buttocks, and on the right buttocks eight long strips of white
skin were transferred after the manner of Thiersch. A strip of human
skin was placed in one section over the frog skin, but became necrotic
in four days, not being attached to the granulating surface. The man
was discharged cured in six months. The frog skin was soft, pliable,
and of a reddish hue, while the human white skin was firm and rapidly
becoming pigmented. Leale cites the successful use of common warts in a
case of grafting on a man of twenty who was burned on the foot by a
stream of molten metal. Leale remarks that as common warts of the skin
are collections of vascular papillae, admitting of separation without
injury to their exceptionally thick layer of epidermis, they are
probably better for the purposes of skin-grafting than ordinary skin of
less vitality or vascularity. Ricketts has succeeded in grafting the
skin of a frog to that of a tortoise, and also grafting frog skin to
human skin. Ricketts remarks that the prepuce of a boy is remarkably
good material for grafting. Sponge-grafts are often
